In this project, I want to display machine name and operation number along with uploaded pdf files based on select machine name and operation number from dropdown menu. This project is working but when I add and select another file in same machine name and operation number, it is displaying two pdf files along with previous pdf file of another machine name and operation number, exactly I don't want it. It should display machine name and operation number along with uploaded pdf file based on select from dropdown menu. And also when I upload another pdf files in same machine name and operation number, it should display two pdf files along with same machine name and operation number within same row.
This project is working fine but I want above validations.
Please anyone can help me out, this will be great for me. Please..

I tried to all the different hx-swap options, but none fix it...It does post correctly and the swap does work, just not sure why I am getting another form in there. Please help
I added the View above. I think thats were my issue is...not sure if I am supposed to be doing this way or not?
Seems like you're trying to render the same html content in your view, which instead should only take a specific element.
You can try to use hx-select="#allergy_target" so htmx will only fetch the table content.
Here, select machine name and operation number, after select and save, It is displaying none instead of data like machine name and operation number in the form of table.
Please help me out to solve this.
I am new in Django.

change your view like this.
def save_machine(request):
if request.method == "POST":
machine_name = request.POST.get('machinename', '')
operation_no = request.POST.get('operationname','')
choiced_machine = Machine.objects.filter(machine_name=machine_name, operation_no=operation_no)
machines = Machine.objects.all()
return render(request,'usermaster/upload.html',{'machines':machines,'choiced_machine':choiced_machine})
Try to edit your form like this below.Currenlty you are not passing any value so that internal server error occurs and you are not getting any response from the server so that None error is showing
<select name="machine_name">
<option>Select Machine Name</option>
{% for machine in machines %}
<option value="{{ machine.machine_name }}">{{ machine.machine_name }}</option>
{% endfor %}
</select>
<select name="operation_no">
<option>Select Operation Number</option>
{% for machine in machines %}
<option value="{{machine.operation_no}}">{{ machine.operation_no }}</option>
{% endfor %}
</select>
In the below scenario, the page is opening but search functionality is not working when i am using {% for i in kitty_list %} in the template. However, when i am using {% for i in kitty %} then I get a NoReverseMatch error.
Url: path('kitty_view',views.kitty_view,name='kitty_view')
View: kitty_list = kitty_list.filter(status = status1)
kittys = kitty.objects.all()
ctx = {'kitty': kitty_list,'kitty_code':kittys}
return render(request, 'kitty/kitty_view.html', ctx)
This is the HTML page which is giving NoReverseMatch error when {% for i in kitty %} is used. When i am using {% for i in kitty_list %} then the page is rendering but the search button is not working.

Inside the template file, you need to modify the below line. {% url 'kitty_view' %} to {% url '<app_name>:kitty_view' %}. If this would not work then, please give me an error in more detail.
My delete view is not working and the error message is:
Page not found (404) Request Method: GET.
I am trying to delete my uploaded file based on its primary key and so far, my url is able to link me correctly based on the pk.
This is my urls.py:
path('post/<int:post_id>/lesson_delete/<int:lesson_id>', LessonDeleteView.as_view(), name='lesson_delete'),
My views.py:
class LessonDeleteView(DeleteView):
model = Lesson
success_url = '../'
template_name = 'lesson_confirm_delete.html'
This is the html template that brings user to the delete view:

<th>Author</th>

{% if l.file %}
{{ l.title }}
{% else %}

{% endif %}

This is my html template for DeleteView:

<div class="content-section" id="main">
<form method="POST">

This is my Lesson Model:
class Lesson(models.Model):
title = models.CharField(max_length=100)
file = models.FileField(upload_to="lesson/pdf")
date_posted = models.DateTimeField(default=timezone.now)
post = models.ForeignKey(Post, on_delete=models.CASCADE, null=False, blank=False)
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('lesson_upload', kwargs={'pk': self.pk})
Is you template called 'lesson_confirm_delete.html'?
Also, for your success url, I have feeling you don't have a path '../'. It should the specific path you want it to go to.
(Sorry, I can't comment yet.)
I use Django paginator to break my search results to few pages
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
In my view I perform the search based on the output from the form

#import pdb; pdb.set_trace()
title = 'payment list'
#import pdb; pdb.set_trace()
if request.method == "POST":

start_date = form.cleaned_data['start_date']
end_date = form.cleaned_data['end_date']
building = form.cleaned_data['building']
payment_list = LeasePaymentFilter(request.GET, queryset=LeasePayment.objects.filter(payment_date__range=[start_date, end_date],lease__unit__building = building ))
paginator = Paginator(payment_list, 25) # Show 25 contacts per page
page = request.GET.get('page')
try:
payment_page = paginator.page(page)
except PageNotAnInteger:
payment_page = paginator.page(1)
except EmptyPage:
payment_page = paginator.page(paginator.num_pages)
else:
payment_list = None
payment_page = None
start_date = None
end_date = None
building = None
else:
payment_list = None
payment_page = None
start_date = None
end_date = None
building = None

return render(request,'payment/payment_range.html', {'form':form, 'payment': payment_list,'page_payment':payment_page, 'start_date':start_date, 'end_date':end_date, 'building':building })
On the top of the page I have a form that I use for search and 2nd part is used to display the results.

My problem is that when my search returns amount of results more than 1 page and I click on next pages. The next pages are always empty.
Any feedback where my problem is?
The problem is that your serch form is POST. So when you click next button you send GET request and if request.method == "POST": part of you view is not triggered.
I suggest you to change serch form to GET:
<form method="GET" action="">
<input type="text" name="q" placeholder="Search" value="{{ request.GET.q }}">
<input type="submit" value="Search">
</form>
And change next button to this:
{% if payment.has_next %}
next
{% endif %}
This will save search value in address bar even after you move to the next page.
